在本实施例中， 所述第二旋风桶 8'的轴心线 17'与第一旋风桶 6'的轴心线 18之间的夹角 a为 135度， 所述第一旋风桶 6，的侧壁 上设有第一抽吸口 7，， 带有灰尘的气流从这里进入第一旋风桶 6， 内， 第一旋风桶 6，内同轴设有圆柱状或圆锥状滤网 13 '。 所述第一 抽吸口 7，相对于第一旋风捅 6'的内侧壁成切向设置，使得从第一抽 吸口 7，进入的空气以与侧壁成切向的方向进入第一旋风桶 6，，以便 在上游旋风分离装置 1，内部建立涡流。 滤网 13，设置在第一旋风桶 6，中央， 所述第一旋风桶 6内部还可以设置集尘桶 5，， 所述集尘桶 5，在上游旋风分离装置 1，底部和下游旋风分离装置的出尘口 11之 间延伸， 并与滤网 13，紧密套合。 上游旋风分离装置 1，初步净化的 空气能通过滤网 13，进入下游旋风分离装置 2，。 从滤网 13，通过的 气流进一步通过设置在上游旋风分离装置 1，和下游旋风分离装置 2，之间的气体通道 3，进入下游旋风分离装置 2，。同时由于在所述的 集尘桶 5，的外表面设置有裙边 22 , 头发、 毛物等被所述的裙边 22 的阻挡而脱落到所述的第一旋风捅 6，中，较小颗粒的灰尘与空气从 所述的过滤孔 23，内向上通过， 实现髙效的上游分离。
所述下游旋风分离装置 2，还可以进一步包括导流管 19， ，在所 述的导流管 19，上开设有出气口 10。 8，上设有出尘口 11，，所述出尘口 11，设置在集 尘桶 5，上部且与所述的集尘桶 5，相连通。 从气体通道 3，流出的气 体进入各个第二旋风桶 8，， 再次净化后的空气经过导流管 19，的内 腔从出气口 10排出，而再次分离的灰尘则通过出尘口 11，掉入集尘 桶 5'内。
所述各个第二旋风桶 8'的轴心线 17，相交于一点， 该点位于所 述的第一旋风桶的轴心线 18，上， 这样的设计能减小整个装置的高 度。
所述上游旋风分离装置 1，上部还包括可拆卸的顶盖 4，，且所述 顶盖 4上设有气流输出口 12，。 从多个第二旋风桶 8，排出的净化空 气通过气流输出口 12，导入到旋风分离装置外部， 再进入负压源。
所述上游旋风分离装置 1，下部还设有底盖 15，，在所述底盖 15， 和第一旋风桶 6，的底部之间设有底部密封圈 24， 可以达到较好的 密封效果。
